This box is approximately 4-1/4" x 2-3/4" x 1" and comes with a hinged lid as well as an inside divider. This Bandage Box is perfect for holding band-aids, antibiotic creams, and small tweezers or you could even use it for a get well gift! The file is compatible with both the 12x12 and 8x12 mats! You can find the tutorial for this box on my blog: http://jamielanedesigns.blogspot.com/2013/10/bandage-box.html
